Lockout
Any failure of the ignition sequence, process trips or flame failure while running results in volatile
lockout of the system. The user is required to press the START/RESET button to reset the system.
Power-cycling the module also resets the system.
In the lock out state all outputs are de-energized except for the Flame Rod (FR). The FAULT LED will
flash a number of times that allows identification of the fault grouping. A 3 second pause occurs once
the code is flashed. This sequence of flashing the code and pausing is repeated until the system is reset.
